News of Monteith’s rehab stint broke over the weekend, when his rep confirmed to People.com that he had “voluntarily admitted himself to a treatment facility for substance addiction,” from which the actor has previously suffered.

Immediately, well wishes from the Glee family followed. “I love and support Cory and will stand by him through this,” Monteith’s costar and real-life girlfriend Lea Michelle told People. “I am grateful and proud he made this decision.”

In a statement, Glee producer 20th Century Fox TV said, “Cory is a beloved member of the Glee family and we fully support his decision to seek treatment. Everyone at the show wishes him well and looks forward to his return.”

Glee — which because of protracted negotiations has yet to be renewed — is set to air its Season 4 finale on May 9.
